Last week we found out that Sandra Bullock donated $1 million to the Red Cross for disaster relief in Japan, so no Gwen Stefani has decided she needs to challenge the actress for the title of America's Sweetheart by doing the same for the Save the Children’s Japan Earthquake-Tsunami Children in Emergency Fund. Well, we'd hope the fashionista behind Harajuku Lovers would do something like that.

"I've been inspired by Japan for many years and have a true love, appreciation and respect for the Japanese people and their culture," Stefani told Us in a statement. "The disaster in Japan is beyond heartbreaking, and I want to do anything I can to help. I would never be able to make a gesture like this without the love and support of all the fans over all these years."

Besides giving a cool mil to charity, the 41-year-old is also planning a limited edition branded t-shirt to benefit the thrice-devastated country, to be sold via NoDoubt.com. We expect a lot more anime-inspired designs in the next season of L.A.M.B. wear, too.
